Hello, yes, I have actually figured out THIS PARTICULAR problem (but still have greater problem). It was due to modifications introduced to the DSK6455.gel files which is responsible for memory mapping.
The problem is that the program that runs on the DSP cannot properly transmit data to the Altera board through the EMIF interface. I have put many printf()'s and GEL_TextOut()'s throughout the program (to see where the program [stops/does nothing]) and the problem occurs due to the fact that the transmitted to EMIF packets should increment a certain counter to a certain value, which would further lead to successful finish of the program, but the counter is not incremented.
I could post the source code as well (3 source files: 100, 200 and 250 lines approximately) if can be helpful, along with the output I am obtaining.
Thank you everyone for helping out.
